UNIFORM CHILD CUSTODY JURISDICTION AND ENFORCEMENT ACT
458-A:14 Jurisdiction to Modify Determination.
Except as otherwise provided in RSA 458-A:15, a court of this state may not modify a child-custody determination made by a court of another state unless a court of this state has jurisdiction to make an initial determination under RSA 458-A:12, I(a) or (b) and:
I. The court of the other state determines it no longer has exclusive, continuing jurisdiction under RSA 458-A:13 or that a court of this state would be a more convenient forum under RSA 458-A:18; or
II. A court of this state or a court of the other state determines that the child, the child's parents, and any person acting as a parent do not presently reside in the other state.
